Anti-IgA1 antibodies
We make 2 antibodies against IgA1 for human, unconjugated or conjugated to biotin. This page explains how they differ, so you can pick the one your experiment needs.
What differs between these antibodies
Which conjugate
Unconjugated antibodies carry no label. You coat a plate with them as the capture antibody, or use them where the antibody itself is the reagent. Biotinylated antibodies are detected with a streptavidin conjugate, such as streptavidin-ALP or streptavidin-HRP.
Capture and detection pairs
To build your own IgA1 ELISA or ELISpot, coat with the unconjugated capture antibody and detect with the biotinylated detection antibody, then a streptavidin conjugate.

About IgA1
IgA1 (Immunoglobulin A1) is one of the two existing IgA isotypes. The proportions of IgA1 and IgA2 secreting B cells differs in various body tissues. Although IgA1 is the most common IgA subclass in serum, IgA represents only 10-15% of the total serum Ig molecules. The IgA found in secretions (secretory IgA or sIgA) is commonly a dimer with two IgA molecules joined by the J chain. Secretory IgA is the most important Ig isotype in mucous surfaces, the area of entry for most pathogens.
